Garden wall render

Question

I have a garden wall around a patio built with thermalite block.  A small portion is a retaining wall but only about 30 cm deep.  What can I use to render the block including below ground surface?  The goal is to finish the block with a smooth surface and paint white.  Location near Peterborough.

Hi Steve you can use sand and cement render but because the garden wall was built with thermalite blocks you will have to sill the blocks with sbr or at times we have nailed galvanized metal lath wire sheets all the best brad

Good evening,

A standard sand and cement render will be the best application
